Chief James Craig said Monday that 31-year-old Precious Allen will be held accountable for the classroom brawl last week at Withrow High School.

Police said Allen, her daughter and another woman burst into a classroom, with mother and daughter assaulting a 15-year-old student with their fists and a combination lock.

The student suffered cuts and bruises, and a teacher ended up with a black eye in the scuffle.

The trio got into the school by walking in the front door while another student was leaving, thereby bypassing the security system that would have otherwise required them to be buzzed in.

"The teacher actually notified the security team before the incident happened; however, it happened quick, and the woman went over to the girl, words were exchanged and she told her daughter to get her," Officer Shawn George said.

Allen is charged with felonious assault and aggravated criminal trespass. Her daughter is facing similar charges, plus assault on a teacher or school bus driver. Another woman, Dawn Brunner, who did not participate in the beating, is charged with criminal trespass.
